Previously the data tool caught all errors and returned them as normal
tool results with error info in the JSON content. This meant pi-agent-core
never saw an exception and always set isError=false in the run-log, even
for rate limit errors (errCode 9001) and other API failures.
Now errors propagate to pi-agent-core which sets isError=true and formats
the error message for the LLM automatically.

UC4 test times out in CI (5s default) because generateSummary's API
provider layer takes longer to fail on slow CI runners. Increase to 15s.

The setTimeout in runSubagentTask was never cleared when childAgent.run()
completed before the timeout. The dangling timer would later reject an
unobserved promise, causing an unhandled promise rejection crash in Node.js
v15+. Capture the timer and clear it in a .finally() block.

Delete sessions-spawn.ts, sessions-list.ts and their tests. Update CLI
to remove waitForSubagents polling workaround (delegate is synchronous).
Update UI, desktop IPC, SWE-bench, and system prompt tests to use the
new delegate tool name.

Replace the async sessions_spawn/sessions_list sub-agent system with a
single synchronous `delegate` tool. The new tool runs tasks in parallel
via Promise.all with per-task timeout, returning combined results directly
in the tool response. This eliminates the need for registry, announce queue,
persistence, and Hub involvement.

The pre-emptive truncation, tool result pruning, and summary fallback
only checked for Anthropic-style `role: "user"` messages with
`type: "tool_result"` blocks. The actual runtime uses pi-agent-core
format with `role: "toolResult"`, `toolCallId`, and `toolName` on the
message itself. This caused truncation and pruning to silently skip
all tool results in real agent runs.
Add handlers for the pi-agent-core format in all four affected modules:
- session-manager.ts: check both "user" and "toolResult" roles
- tool-result-truncation.ts: new handler for toolResult format
- tool-result-pruning.ts: new processToolResultMessage() + updated loops
- summary-fallback.ts: include "toolResult" in artifact ref extraction
Verified via agent-driven E2E tests (5 test sessions, 6 artifacts).

- Add real user messages for bootstrap protection in pruning tests
- Fix artifact directory path assertions (baseDir vs sessions/baseDir)
- Add cross-phase tests (Phase 1 truncation → Phase 2 pruning)
- Remove conditional assertion guards that could silently skip checks
- All 30 E2E integration tests now pass with mandatory assertions
